Sam, the Library Mouse, and his friend Sarah's adventures continue. When they wake to find the library being packed up to prepare for a major renovation, they realise they won't have a home during construction. So off they go in search for a place to live. Of course Sam knows research is key, so he finds them books about architectural styles so they can build temporary homes (from things found around the library). They build and live in a variety of houses: a castle, an igloo, a yurt, a Modern house, even a geodesic dome--but none feel like home to Sam. Finally the renovation of the library is complete and they can move back home. The book includes backmatter of photos of real house styles discussed in the book and a brief glossary of terms.
